' To all whom it mag concern:

Be it known t at I JOSEPH P. HASTY,

a citizen of the United States, residing at Belleville, in the county of Republic and State of Kansas, have invented a new and useful Switch-Stand, of which the following is a specification.

The present invention appertains to switch stands or switch throws, and aims to provide a novel and improved device of that character which can be used either as a single switch stand or three-way switch stand.

Another object of the invention is to provide a novel means in a switch stand for transmittin the ower, in order that the switch can e rea ily actuated by hand in a most efi'ective manner.

Another object is the rovision of a switch stand wherein the wor g parts are protected from the elements. A still further object is the provision in a switch stand of the nature indicated, of novel means for controlling andlocking the rotation of the operating shaft.

It is also the object of the invention to provide a switch stand having the characteristics above noted, and which is comparatively simple, compact and inexpensive in construction, as well as being thoroughly practical and efiicient in use.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts andin the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the inventlon herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is an elevation of the switch stand, portions being broken away. 1

Fig. 2 is 'a vertical section taken on the line 22 of Fig. 1.

Fi 3 and 4 are sectional details taken on t e respective lines 3-3 and 4-4 of Fig. 5 is a dia ammatical view of the cam, illustrating t e periphery thereof laid out flat.

The numeral 1 designates the upright body or stand proper, which is constructed of suitable metal, and which has a suitable base 2 adapted to be secured upon the ties or other foundation, said body 1 being provided with a chamber or cavity 3 in the lower portion thereof opening downwardly to house some of the working parts and protect them from the elements. The upper end of the body ,1 is provided with an annular outstanding flange 4, and a vertical shaft or staff 5 is journaled for rotation through the upper portion of the body 1 Patented Mar. 12, 1918.

and projects downwardly within the chamher 3. The upper end of the shaft 5 carries a suitable signal 6.

As a means for transmitting the motion from the actuating shaft 5, a cylindrical cam 7 is secured upon the lower portion of said shaft within the chamber 3, and is provided with a circumferential cam groove 8, provided with a portion 9 extending throu h substantially one half of a circle and isposed in a common plane at right angles with the shaft 5, said groove 8 having an ofiset cam portion 10 also extending through substantially one half of a circle. The lower end of the cam 5 is journaled or swiveled through a strip or bar 11 terminally secured to the base 2 and extending across the mouth of the chamber 3. The strip 11 is provided adjacent to its opposite edges with upstanding bearings 12 to which are pivoted the elbows of bell crank levers 13. Said levers have depending arms to which links or rods 14 are connected, and said rods are connected in any suitable manner with the switch points. When two levers 13 are employed, the switch stand is of the three-way type for operating a double switch, but when a single switch only is operated, one of the levers 13 and corresponding rod or link 14 can be eliminated. The upper arms of the lovers 13 carry rollers 15 working in thecam groove 8 and disposed diametrically o posite to one another. .Thus, as the shaf t 5 is rotated, one of the rollers 15 will work in the portion 9- of the groove 8, while the other will work in the cam portion 10. One lever 13 is thus held stationary, while the other lever whose roller 15 works in the portion 10 of the groove 8 will be swung for actuatin the corresponding link 14. By turning the aft bracmg the shaft 5, and secured thereto by means of a rivet 18 or other suitable secur- Y ingelementil-lwhereby the shaft 5 turns with 5, the cam when operated in one direction will swing one lever, and when operated in the other direction will swing the other lever, either lever when swung being. returned to normal position when the cam-is returned to normal position with the shaft 5.

A cap 16 is fitted over the upper end of vided with a central upstanding boss 17cmthe cap. T scap16 sheds water'and sleet, and thereby protects the parts underneath it. A web portion 19 extends radially from the boss 17 and upwardly from the cap 16, and is provided with a downwardly and outwardly opening recess .20, the portion 19 having a tongue 21 projecting therefrom overthe outer end of the recess 20 to extend at an angle therefrom and provided with an aperture 25. The flange 4is provided 7 at suitable points thereof with notches 26 into which the lever 22 can swing downwardly when the shaft 5 isibrought to different positions for setting the switch or switches in the desired positions. When the lever 23 is swung upwardly, it is removed frormthe corresponding notch 26, and the lever can then be swun torotate thu'shaft 5 in either direction. en the lever 23 is swung downwardly into anyone of the notches 26, the apertured end ofthe car.

24 is swung outwardly to project from the portion 19, and a padlock or other suitablelockcan then be engaged with the apertured the shaft 5, a sto 27 is carried by the ri y 1, said upper end of the per end of the b body being provided with aperturw-or sockets 28 for the adjustable reception of one or more stops 27, to limit the movement I of the lever 22. When the lever 22 is raised for rotatingthe shaft 5, the inner or upper end of the lever is swung downwardly against or adjacent to the upper end ofthe body 1, and as the lever 22' is swung, the

same will strike the-stop 27 when the lever is moved over one-notch 26. Two of the stops 27 can be used, if desired, and the sto s can be adjusted to different positions fgr limiting the movement of the shaft 5 acthe body at various saidshaft, said end 0 the body having adjustablemeans under the cap for limiting .tical shaft journal provided with an annular groove 29 for receiving the stop 27.
